do you sharpen your brand new blades?

brand new blades seem dull like a butter knife edge to them

i have been told that is just the paint/powder coat that makes it "seem" dull but they are plenty sharp underneath after that comes off as soon as its in use

i always sharpen new blades to a razor edge before installing them but im curious what you guys think is needed or not needed

im pretty sure even dull edge blades will cut just fine albeit not cleanly

the reason i ask is, is the factory edge sharp enough or is it just formed to shape and its intended to be sharpened before using

You can only learn if you ask the question, so there are no dumb questions.

Never had a problem with new blades being dull. Push mower or Rider mower.

I've never sharpened a new blade. I used to sharpen blades to the point I could shave with them but found that thin edge wore back off pretty quick and if you hit something even a twig you have more of a chance of taking a chunk of metal out of the blade. I still file them sharper then what the new ones seem to be sharpened but have relaxed it a bit on how far I go beyond that.

If you sharpen blades to a razor edge, that will be gone after one cutting I'm sure.
